The former Hannah Montana star ended months of speculation about their rocky romance on Monday by announcing that she and Australian actor Hemsworth had called off their engagement after almost four years together.

The news emerged two days after The Hunger Games hunk was snapped flirting with Gonzalez at a Las Vegas nightclub on Saturday, and it appears a new relationship is already blossoming after they arranged to meet up again in California.

They spent time together on Monday and on Tuesday, Hemsworth was spotted at Gonzalez's Beverly Hills apartment block, where they were caught on camera kissing before the actor headed to his car and drove off.

Gonzalez, 23, reportedly moved to Los Angeles earlier this summer, after breaking up with her boyfriend to pursue a career in Hollywood, according to Eonline.com.

Meanwhile, Cyrus, 20, is preparing to put her love troubles behind her by heading to Sin City this weekend to perform at the iHeartRadio music festival, alongside the likes of Sir Paul McCartney, Sir Elton John, Justin Timberlake, Katy Perry and Drake.
